You can set expiration times for shared links in Drobox too - if you're a pro/biz user - which I'm not and clearly a lot of people aren't.
But even at that, you still have to remember to delete the files.

To me this reminds me of https://www.sharefest.me/ i like the fact you can specify length of time to temp store on Yttr.
Thanks for the support! Yttr was created with the simple idea of sharing temporary files without the bureaucracy of existing services.
Any feedback is appreciated. :)
By the way, there's some "easter eggs":
• Press "Z" to compress your file while uploading;
• Paste some text on the homepage. Very useful for sharing code snippets.
